To check the air pump take off the two hoses that go into it , drive the truck and if it dont baqckfire thats probly the problem.As for the egr the best way without some kind of emmisions test is to try a new one.You can also check the pcv by taking it out and shake it, if it rattles its fine but if it dont then its clogged.
I hope this helps a little ..good luck
